from class:

Advanced Chemical Engineering Science

Definition

Parametrization is the process of expressing a set of variables or equations in terms of one or more parameters, allowing for a more simplified representation of complex systems. In the context of various scientific fields, particularly those involving quantum mechanics and molecular dynamics, parametrization enables researchers to model and analyze intricate phenomena by reducing the number of variables and making calculations more manageable.
